To the 8 rear of the platform D a hand wheel shaft f is suitably mounted and connected. with the rear end of the plow beam by means of a rack bar having a rack f which engages the pinion on said shaft. Both of said hand wheel shafts are disposed longitudinally and horizontally, and said shaft f is held against back rotation by a ratchet. With this arrangement the operator on the platform D can easily raise and lower the plow at will.

The elevator G is disposed longitudinally of the machine, and has its front and lower end in position to receive the soil from said plow. It will be seen that said elevator is hung between the side beams a a of the body frame, and that it is oblique to the line of travel that is to say, the forward end of said elevator is positioned to one side of the for the broader purposes of my invention do not so limit myself; to provide an improved and more efficient arrangement 0 the plow, and the means for raising anc 0 lowering the same; to provide an improved arrangement of the elevator and the means for operating and raising and lowering the same; to provide improved means for discharging the soil at either side of the ma- 5 chine, and for operating and controlling the same; and to provide certain details and novel combinations and features of improvement tending to increase the general e ciency of a machine of this particular char- To the foregoing and other useful ends, my invention consi ts in matters hereinafter set forth and claimed.

Said shaft H is driven by a sprocket chain 71 from the rear axle I, and the transmission of power is cona suitable clutch 2', operated by a hand lever 2' The shaft H is also supported in the bracket bearings 72 on the frame.

he transverse and reversible conveyer J is disposed below the rear end of the elevator, and travels on shafts j mounted in bracket bearings 7' on the body frame. Said shafts are connected by a sprocket chain which travels around idlers j and the lower driving sprocket j on the longitudinal shaft This shaft is mounted in bearings on the frame, and is provided with a bevel pinion j engaging the bevel gears j and 7' on A reversing clutch j is interposed between said gears and controlled by a hand lever 7' whereby the conveyer J can be run in either direction.

As shown, the laterally projecting conveyers K and are similar in construction and operation, and serve for discharging the soil from the rear of the machine, at either side thereof. The lower ends of said swinging conveyers are supported by their operating shafts 7c and Z, and their upper and outer ends are supported by chains and Z running over the sheaves 72 and Z and then wound on the longitudinal hand wheel shafts 70 and Z These sheaves and hand wheel shafts are, it will be seen, mounted on the uprights of the frame or superstructure M, in any suitable manner. Ratchets are provided for preventing back rotation of said hand wheel shafts. The said conveyers are driven by sprocket chains 76 and Z which eX- tend from their outer ends to the short longitudinal shafts in and Z which latter are mounted in bracket bearings at opposite sides of the machine. The short shafts 7c and Z are likewise mountec, and are connected with the shafts and Z by means of sprocket chains 1: and Z and with the shaft by means of bevel gearing 76 and Z as shown. The clutch N associated with the gearing 70 controls the transmission of power to the conveyer K, and is operated by a hand lever a. The clutch O associated with the gearing Z controls the transmission of power to the conveyer L and is operated by a lever 0.

From-the foregoing it will be seen that I provide an improved and highly efficient grader which can discharge the soil at either side, and in which the elevator can be regulated independently of the means for demachine,

side thereof, the forward end of the plow beam, and means including a vertically disposed rack bar and a ing and lowering the plow hold the livering the soil from the machine. lVagons can be loaded alternately at opposite sides of the machine, without stopping the latter to change wagons, and thus the loading of wagons is greatly facilitated in a grader having a plow only at one side thereof. Either swinging conveyer can be drawn up to permit the machine to run close to a bank or anything else, and the means thus provided for delivering the soil from the machine can be regulated independently of the elevator. The plow is easily raised and lowered, as is also the elevator. In fact the machine as a whole represents an advanced type of elevating grader, and its advantages will be obvious to those familiar with this art.
